Abstract
Embodiments may disclose a vision system for detecting a defect, including a conveyer belt configured to move at least one bottle through the vision system; a light emitting diode (LED) backlight configured to silhouette any dark contamination on a surface or inside the at least one bottle; a robot with a bottle gripper tooling, the robot configured to pick up the at least one bottle and rotate the at least one bottle; at least one camera configured to take pictures of the at least one bottle while the at least one bottle is being rotated; and a flipper arm configured to stop or allow the at least one bottle to move to a position where the robot picks up the at least one bottle.
Claims24
A vision system for detecting a defect, comprising:
- a conveyer belt configured to move at least one bottle through the vision system;
- a light emitting diode (LED) backlight configured to silhouette any dark contamination on a surface or inside the at least one bottle;
- a robot with a bottle gripper tooling, the robot configured to pick up the at least one bottle and rotate the at least one bottle;
- at least one camera configured to take pictures of the at least one bottle while the at least one bottle is being rotated;
- and
- a flipper arm configured to stop or allow the at least one bottle to move to a position where the robot picks up the at least one bottle.
A method of detecting defects in a vision system, comprising:
- inputting a picture, taken by at least one camera, of at least one bottle;
- inputting manual regions, each manual region defined by a plurality of zones, which correspond to the picture taken by the at least one camera;
- performing a histogram by calculating grayscale values of each zone;
- setting a threshold value of each zone based on the histogram;
- comparing the threshold value of each zone with the calculated grayscale values;
- and
- rejecting the at least one bottle if any of the calculated grayscale values is greater than the threshold value of each zone.
A method of defecting defects in a vision system, comprising:
- inputting a picture, taken by at least one camera, of at least one bottle;
- inputting a large manual region, the large manual region corresponding to the picture taken by the at least one camera;
- inputting a small manual region for sequentially sweeping through the large manual region, the small region corresponding to the large manual region;
- performing a histogram by calculating grayscale values of each small region;
- setting a threshold value of each small region based on the histogram;
- comparing the threshold value of each small region with the calculated grayscale values;
- and
- rejecting the at least one bottle if any of the calculated grayscale values is greater than the threshold value of each small region.
